Best device for Gigabit Ethernet traffic testing and WiFi Site Surveying

bobalexander

Hi everyone!

I am currently using a Raspberry Pi 2 running IPERF https://iperf.fr/ to test bandwidth on a WiFi/LAN network.

As the Pi is only 100Mbps I am only able to exercise tests up to the 100M mark (~96 Mbits/sec).

 

Is anyone aware of a better small platform that I could setup iperf on to run tests at a higher bandwidth?

Ideally, it could run at GigE speeds but my current needs only require ~450Mbps for 802.11n WiFi testing.

BTW, this is nothing permanent or attached to a production network so security is not a concern.

 

Thanks!

    In case anyone is interested, I have ran a few tests while connected to the AP at 5.8Ghz 802.11n (450Mbps)

    I was able to average 133.125 Mbits/sec with a peak of 144 Mbits/sec with no tuning or tweaking:

    was the source on the WIFI as well or connected via copper?

     

    Also are you sure the USB WIFI adaptor is capable of using all that bandwidth offered..

    Personally I think that's very good either way getting a 1/3 of the max available bandwidth in real life!

    The source (Banana Pi) in the WiFi test was connected to the AP (Cisco 2702i in autonomous mode) via GigE copper straight in.

    The WiFi adapter in my laptop is an internal PCI Express Half Mini Card (Intel - Centrino Ultimate-N 6300 AGN).
